[0033] Example 2

[0034] The present invention provides a technical solution: Figures 1 to 6As shown, the present invention provides a chuck-type high-voltage equipment detection device, comprising a connecting sleeve 1, the inner cavity of the connecting sleeve 1 is movably connected to an extended connector body 5, the outer side of the extended connector body 5 is movably sleeved with a first connecting pipe 2, the outer side of the first connecting pipe 2 is movably sleeved with a second connecting pipe assembly 3, the bottom of the extended connector body 5 is fixedly installed with an electric detection and discharge rod 4, the upper end of the first connecting pipe 2 is movably connected with a fixing assembly 6, and the lower end of the first connecting pipe 2 is fixedly installed with a high-voltage reducer 7.

[0035] The above scheme is adopted: the connecting sleeve 1 is installed on the surface of the tooling through the cooperation of the first connecting tube 2 and the second connecting tube assembly 3, and the chuck in the middle of the connecting sleeve 1 is rotated to make the connecting sleeve 1 and the tooling stable. The chuck is a device for clamping the workpiece, and the workpiece is clamped and positioned by radial movement of the movable claws evenly distributed on the chuck body, and the chuck is a prior art. Then, the second connecting tube 301 is moved, and the second connecting tube 301 is rotated after adjusting to the required height, so that the rectangular block 309 in the inner cavity of the second connecting tube 301 is clamped on the two convex parts on the outer side of the first connecting tube 2. The clamping blocks 307 are pulled toward both sides so that the clamping blocks 307 and the moving blocks 305 are no longer clamped, and the first spring telescopic rod 304 drives the moving block 305 and the fixed rod 308 to contract, so that the two groups of fixed rods 308 move to the inner cavity of the second connecting tube 301, so that the fixed rod 308 blocks the rectangular block 309 to prevent the rectangular block 309 from moving and causing instability in the second connecting tube assembly 3, thereby completing the extension of the electroscope device and avoiding the operator from climbing back and forth. Safety hazards may also occur when the operator climbs due to the unstable ground.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, the second connecting pipe assembly 3 includes a second connecting pipe 301, which is movably connected to the first connecting pipe 2. A fixing ring 302 is fixedly installed on the upper end of the outer side of the second connecting pipe 301, a rectangular block 309 is fixedly installed on the upper end of the inner cavity of the second connecting pipe 301, a fixing block 303 is fixedly installed in the middle of the fixing ring 302, a first spring telescopic rod 304 is fixedly installed on the side of the fixing block 303 away from the first connecting pipe 2, a moving block 305 is fixedly installed on the end of the first spring telescopic rod 304 away from the fixing block 303, a second spring telescopic rod 306 is fixedly installed on one end of the fixing ring 302, a clamping block 307 is fixedly installed on the end of the second spring telescopic rod 306 away from the fixing ring 302, a fixing rod 308 is fixedly installed on the side of the moving block 305 close to the first spring telescopic rod 304, and the fixing assembly 6 includes a semi-ring 601, which is movably connected to the first connecting pipe 2, and a butterfly nut 602 is threadedly connected to one side of the semi-ring 601.

[0037] The above scheme is adopted: the second connecting tube 301 is moved by cooperating with the fixing ring 302, and the second connecting tube 301 is rotated after adjusting to the required height, so that the rectangular block 309 in the inner cavity of the second connecting tube 301 is clamped between the two protrusions on the outer side of the first connecting tube 2, and the clamping block 307 is pulled to both sides so that the clamping block 307 and the moving block 305 are no longer clamped, and the first spring telescopic rod 304 drives the moving block 305 and the fixing rod 308 to shrink, so that the two groups of fixing rods 308 move to the inner cavity of the second connecting tube 301, so that the fixing rod 308 blocks the rectangular block 309 to prevent the rectangular block 309 from moving and causing the second connecting tube assembly 3 to shake, and the two half rings 601 are closed by cooperating with the butterfly nut 602, and the butterfly nut 602 is screwed to fix the first connecting tube 2.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the connecting sleeve 1, the test and discharge rod 4 and the extended connector body 5 are connected, a chuck is provided in the middle of the connecting sleeve 1, a plurality of small protrusions are provided on the outer side of the first connecting tube 2, and the length between the two protrusions is the same as the length of the rectangular block 309, two groups of semi-rings 601 are provided, and the two groups of semi-rings 601 form a circle when hinged and closed, grooves are provided on both sides of the moving block 305, and the clamping block 307 is movably connected to the groove, a slot is provided at the upper end of the second connecting tube 301, and the fixing rod 308 is movably connected to the slot, the length of the fixing rod 308 is greater than the length of the rectangular block 309, the rectangular block 309 is arc-shaped, the clamping block 307 is "L"-shaped, and a rubber strip is provided at the lower end of the second connecting tube 301.

[0039] The above scheme is adopted: through the design of the connecting sleeve 1 and the electric test discharge rod 4, the connecting sleeve 1, the electric test discharge rod 4 and the extended connector body 5 are connected, so that when the connecting sleeve 1 is installed, the gas generated by the extrusion passes through the extended connector body 5 and is finally discharged from the electric test discharge rod 4, so that the electric test device is more stable. Through the design of the first connecting tube 2, the length between the two protrusions is designed to be the same as the length of the rectangular block 309, so that after the second connecting tube 301 is rotated, the second connecting tube 301 drives the rectangular block 309 to rotate, so that the rectangular block 309 is just stuck between the two small protrusions, and the semi-ring 60 1, the two groups of half rings 601 form a circle when closed, so that the butterfly nut 602 is rotated, and the butterfly nut 602 closes the two half rings 601, thereby fixing the first connecting tube 2 and the extended connector body 5. Through the cooperation of the moving block 305 and the clamping block 307, the design of the groove makes it possible for the clamping block 307 to clamp the moving block 305 when the height of the second connecting tube 301 is adjusted, so that the fixing rod 308 no longer enters the inner cavity of the second connecting tube 301, thereby not blocking the rectangular block 309. After adjusting the height, the clamping block 307 is moved from the moving block 305 to the inner cavity of the second connecting tube 301. The first spring telescopic rod 304 is retracted to drive the moving block 305 and the fixing rod 308 to move into the inner cavity of the second connecting tube 301, thereby shielding the rectangular block 309 and ensuring the stability of the height adjustment. Through the cooperation between the second connecting tube 301 and the fixing rod 308, the fixing rod 308 is movably connected to the slot, so that the fixing rod 308 shields the rectangular block 309, ensuring the stability of the second connecting tube assembly 3 after the position is adjusted. Through the design of the fixing rod 308 and the rectangular block 309, the length of the fixing rod 308 is greater than the length of the rectangular block 309. The length value allows the fixing rod 308 to completely cover the second connecting tube 301 after entering the inner cavity of the second connecting tube 301, thereby preventing the rectangular block 309 from moving, thereby ensuring the stability of the second connecting tube assembly 3. The shape of the rectangular block 309 allows the rectangular block 309 to fit the inner cavity of the second connecting tube 301, thereby allowing the rectangular block 309 to be snap-fitted to the first connecting tube 2. Through the design of the second connecting tube 301 and the design of the rubber strip, when installing the second connecting tube assembly 3, the hand slipping phenomenon when moving the second connecting tube 301 is avoided, and it is easy to install during use.

[0040] The working principle and use process of the present invention:

[0041] When in use, connect the connecting sleeve 1 with the extended connector body 5, install the connecting sleeve 1 on the surface of the tooling, rotate the chuck to make the connecting sleeve 1 and the tooling more tight and stable, and it is more labor-saving to rotate the chuck and easier to install, so it can be directly installed in place. According to the position adjustment of the high-voltage tester to be measured, the first connecting tube 2, the second connecting tube assembly 3 and the extended connector body 5 are installed, the first connecting tube 2 is sleeved on the outside of the extended connector body 5, the two half rings 601 are closed, the butterfly nut 602 is screwed to fix the first connecting tube 2, and then the second connecting tube 301 is moved. After adjusting to the required height, the second connecting tube 301 is rotated so that the rectangular block 309 in the inner cavity of the second connecting tube 301 is stuck between the two protrusions on the outside of the first connecting tube 2, and the clamping block 307 is pulled to both sides so that the clamping block 307 and the moving block 3 05 is no longer stuck, the first spring telescopic rod 304 drives the moving block 305 and the fixed rod 308 to shrink, so that the two groups of fixed rods 308 move to the inner cavity of the second connecting tube 301, so that the fixed rod 308 blocks the rectangular block 309 to prevent the rectangular block 309 from moving and causing instability in the second connecting tube assembly 3. During installation, the gas generated by the extrusion of the connecting sleeve 1 is discharged from the hole at the bottom of the extended connector body 5, making the installation simpler and the service life longer, avoiding unstable installation. After the test is completed, it is directly removed and the next position is tested. The testing process is simple and easier to install, so as to better detect the withstand voltage, partial discharge and impact of the high-voltage equipment, thereby avoiding the operator from consuming a lot of time when climbing back and forth, and avoiding the situation where the operator has safety hazards when climbing due to unstable ground.
